WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 270,591, dated January16, 1883.

Application filed June 22, 1882. (No model.)

T all whom it may concern:

Be it known that we, ANDREW INGLIS, AN- DREW J. INGLIS, and CHAR-LESINGLIS, of Horicon, in the county of Dodge and State of Wiscousin, haveinvented certain new and useful Improvements in Wind-Wheels; and we dohereby declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

()ur invention relates to an improvement in wind-wheels, the object ofthe same being to provide positive means for regulating or feath-' eringthe fans or wings of the wheel.

A further object of our invention is to providesimple and efficientmeans for transmitting the motion from the revolving main shaft to theoperating-rod; and with these ends in view our invention consists in theparts and 2:) combination of parts, as will be more fully de-.

scribed, and pointed out in. the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view ofour improvement. Fig. 2 is a view showing the manner of conneeting themain shaft to the operating-rod. Fig. 3 shows the relative positions ofthe hubs when the fans are in open and closed adjustment, and Fig. 4 isa modification.

A represents any suitable standard or base, 0 provided at the upper endwith a metallic bearing-plate, B, and slightly below the latter with theguide-bearing G. This plate B and bearing 0 are centrally perforated forthe passage of the downwardly-projecting tube D,

55 which latter is rigidly secured atits upper end to the turn-table E.This turn-table rests and turns on the bearing-plate B, and is providedwith a hollow cylindrical arm, F, arranged at right angles to the tube Dand adapted to 0 contain the main shaft G. The hollow arm F isrigidlysecured near its inner end to the turntable, and is provided withthe two laterallyextending arms a, adapted to hold and guide theregulating-levers I.

To the loose hub H the main stays or arms H of the wind-wheel arerigidly secured through the intervention of the radial arms I), whichlatter are rigidly connected to the hub or formed integral therewith.This hub H, as

before stated, is loosely secured to the hollow arm F, and is free tomove longitudinally, but

is prevented from turning thereon independent of the hub J, by meanswhich will hereinafter be. more fully described. The rear end of thishub H, or the end nearer the standard A, is provided with acircumferential groove,

0, in which the collar 01 rests, the latter being provided with two sideears, bymeans of which the regulating-levers I are secured thereto.

J is a hub rigidly secured to the main shaft G, and provided with thearms 6, each latter having an opening at its outer end for the passageofthe guide-rodsf. These guide-rodsf (two in the present instance) arerigidly secured on opposite sides of the hub H to the arms I), whichlatter are enlarged for that purpose, and extend forward and passthrough the apertures in the arms 0.

As the hub J is rigidly secured to the shaft G, and the hub H looselysecured on the arm F, it follows that-as the wind-wheel revolves therotary motion of the hub H, to which the wheel is secured, istransmitted to the hub J through the intervention of the guide-rodsf.This construction relieves the hollow arm F of all torsional strain, andtransfers it directly to the shaft G, and equalizes the matter bytransferring the weight of the wheel to the arm F.

As the rotary shaft does not sustain the weight of the wheels, as inwind-wheels heretofore coustructed,itwill beobserved that there iscomparatively little wear on the bearings of the shaft, audit is notlikely to sag at its outer end. A much lighter and-less expensive rotaryshaft may be used than is required in those windmills where the wheel iscarried by the rotary shaft.

Besides the connection between the hubs H and J already referred to, thelevers K and L help to strengthen the connection, and at the same timeperform another function-viz., to feather the fans or wings when it isdesired to throw the wheel from the wind. The longlevers K are pivotallyconnected at one end to the earsgof the hub H, and extend outward there-5 from, and are secured at their outer endsto the inner end of thelevers M. The opposite ends of these levers M are secured to the fans itbelow their pivotal connection with the wheel-stays. The shortleversLare pivotally secured to the hub J, and extend inward toward thelevers K, and are pivotally connected to the said levers at or near thecenter thereof. Thus itwill be seen that by moving the hub H toward theend of the arm F, or toward the hub J, the levers L move the levers Kbackward until they stand in the same or nearly the same plane as thearms fof the hub H. As the levers K are forced backward, they also movethe levers M outward and open the fans.

The regulating-levers (two in number) are situated on opposite sides ofthe hollow arm F, and, as before stated, are secured at their outer endsto the clutch or collar engaging the hub 11. These levers run parallelfor a suitable distance, and at their rear ends converge and bendupward, so as not to obstruct the operation of the crank mechanismsituated at the rear end of the shaft G.

is a weighted lever, pivotally secured to the rearwardly-extendingarm Iand provided with an upward extension or arm, 11, by means of which thesaid weighted lever is connected to the regulating-levers through theintervention of the link Q. The inner end of this weighted lever O restsover the downwardly-projecting tube l), and is provided with a hole oropening by means of which the regulating rope or chain is securedthereto. The lever O is so constructed and weighted as to keep the fans.

down to the wind; but when the wind increases in force and acts directlyagainst the face of the wings or sails of the wheel it forces the hub Htoward the hub J, which causes the said wings or sails to change theirposition to the wind, so that its force upon them is diminished. Theweighted lever acts as an automatic governor,and causes the wheel toturn regularly, irrespective of the varying velocity of the wind.

\Vhen it is desired to open the fans it is simply necessary to pulldownward on the regulating cord or rope, which depresses the inner endof the lever O, elevates the rear end, and

moves the hub H toward the hub J by means of the levers and links beforedescribed. The fans can be held in this open adjustment by simply tyingthe end of the cord to the stamiard after the fans have been opened.

The shaft G extends throughout the entire length of the hollow arm F,and is provided at its inner end, just beyond the said arm, with thefaceplate It, to which the wristpin S is secured. This wrist-pin isprovided with the sliding block I, which latter moves in the groovedlever U, the said latter being pivotally secured at one end to theturn-table and connected to the operating-rod b, directly over thedownwardly-projecting tube D. The sliding block T is pivotally securedto the wristpin S, and as the shaft G revolves the said block moves inthe groove in the lever U, and alternately elevates and lowers theoperatingrod 1/. The operating-rod I), being attached to the lever U,will receive an up-and-down motion to every revolution of the-shaft G,the up motion being slow and the down motion fast.

Instead of providing the wrist-pin with the block before described, itcan be dispensed with, and a simple roller, employed instead thereof,will answer all the necessary purposes.

The lower end of the operating-rod can be secured to a pump rod orhandle, or connected to any sort of mechanism capable of receiving itsmotion from a wind-wheel.

The grooved lever U is pivoted to the standard s, which latter issecured to the turn-table, a little to one side of the face-plate on therevolving shaft. This grooved lever is open at both ends, which preventsthe possibility'ot' snow packing in the groove and retarding theoperation of the wheel. \Vhen the grooved lever rests in a horizontalposition the upper I end of the operating-rod rests directly oppositethe center of the revolving shaft, or at a point within the horizontaldiameter of the circle made by the wrist-pin on face-plate. Thisconstruction enables the mill to make nearly twothirds of a revolutionwhile the pump-rod is being raised and about one-third while the rod isdescending. This is a great advantage, as no power is expended inlowering the rod. 111 all other constructions of mill one half of thepower of the mill is employed in elevating the operatingrod and theother half in lowering the same.

The wheel is kept to thewind by any suitable vane or means best suitedfor the purpose.

Another modification of our improved device is shown in Fig. 4. In thisconstruction the hub J, with its arms, and the guide-rods are dispensedwith and the hub H made to perform the functions of the two hubs. Inthis construction the hub H is made large at its rear end to rest on thearm I and small at its front or outer end, so as to closely embrace theshaft G. The hub H is also divided, the portion thereof with thecircumferential groove thereon being separated from the remainingportion. The levers K are connected to this separated portion, and thelevers L to the ears of the hub H. In this construction only theseparated portion of the hub slides on the arm F; but the operation andfunction of the remaining portions remain the same as described in thefirst construction.

Our im proved machine is simple in construction, is of few parts, isdurable and efficientin use, and can be positively regulated andcontrolled in a few moments without any trouble whatever.

It is evident that slight changes in the construction and arrangement ofthe different parts might be resorted to without departing from thespirit ot' our invention, and hence we would have it understood that wedo notlimit ourselves to the exact construction shown and described, butconsider ourselves at liberty to make such changes as come within thespirit and scope of our invention.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

1. In a windmill, the combination, with a turn-table and ahollowcylindrical arm secured thereto, of a revolving shaft journaled withinsaid hollow arm, a wheel-hub looselymounted upon said arm, an outer hubrigidly mounted on the revolving shaft, and connected to the wheel-hubby pivoted links, and guiderods, substantially as set forth.
